Demco Hydraulic Brake Actuator Reverse Lockout Solenoid Installation Video

Hey Richard, thanks for reaching out! The Dexter DX7.5 Drop-N-Go Brake Actuator #099-175-00 is a great option for a replacement actuator because it's a direct replacement for the common Model 60 actuators that were popular in the '90s.…

Hello Bob, For your Demco DA70 actuator use the Reverse Lockout Solenoid #DM11993. The difference between this and #DM5837 is that the latter comes with a cover.

I do have an option for you but the coupler on your trailer is very old and we simply don't carry parts for them anymore as they were discontinued by the manufacturer. Therefore, the only option we can offer is a new coupler, the Demco Hydraulic…

Thank you for the picture, it is helpful. I can see that you have an actuator for disc brakes. In the picture you can see the yellow label that says "disc brake actuator for use with disc brakes only". The coupler does not differentiate…

Hey Al, so we have a solution but since disc brakes require a higher PSI than drum the #DM62VR would not work on drum brakes. Instead you'd want to go with the part #DM72VR which is basically the exact same thing but made for drum brakes. You can…

You do not necessarily need to replace the hub and drum assemblies on your 1990 Four Winns Tandem Axle Boat Trailer as long as they are still in good shape. The only way to tell will be removing them and checking the inside where the brake pads and…
